MOUNTING MEANS Filed Jan. 18, 1934 /N l/E N 70/? HARRY A. DOUGH-A5 Patented Sept. 7, 1937 UNITED STATES PATENT OFFICE MOUNTING MEANS Harry A. Douglas, Bronson, Mich., assignor to Kingston Products Corporation, a corporation of Indiana This invention relates to mounting means adapted particularly for incandescent electric lamps.

The invention is of particular utility when employed in conjunction with dash lamps for automotive vehicles and the like, and, among other objects, aims to provide an improved and economical mounting which combines, in a one piece structure, both a retaining means for the lamp socket and a cowl for the lamp whereby the light thereof is suitably directed, as through the instrument board when employed as a telltale light indicator.

Other objects and advantages will be apparent from the following description, taken together with the accompanying drawing, showing illustrative embodiments of my invention in which Figure l is a side elevation parts being shown in section, showing one embodiment of my invention;

Figure 2 is a longitudinal sectional view of parts included in Figure l and being a section taken on the line 22 of Figure 3;

Figure 3 is an end View of the structure of Figure 2 taken from the left hand side.

While not necessary to this invention, it is preferable to construct the housing for receiving the lamp and lamp socket as taught in this applicants prior copending application, Serial No. 6%,282, flied November 25, 1932, which issued as Patent No. 1,9789% on October 30, 1934, but

other types of housing construction may be used without departing from the scope of the invention.

In the embodiment of this invention illustrated, the housing I is preferably struck from a rectangular blank of somewhat resilient sheet metal, such as brass, and bent longitudinally to substantially cylindrical form with the transverse edges 2 brought together to form a split spring."

end of the housing I and after receiving the fin gers l the ears 5 are bent down to engage the outer wall of the housing. It is also preferable in forming the blank to strike out tongues 8 on the end opposite the circular extension 4 which may be slightly contracted when the blank is ble to the driver when the lamp I is energized bent to form the housing I to enhance the function of the housing in resiliently retaining the socket 9 which is received therein together with a commercial incandescent lamp lil mounted in the socket. The housing may be provided with indentations H to limit the insertion of the socket therein. The socket 9 may also carry the usual current conductors 12 shown in Figure 2 as spring pressed into engagement with the contacts I3 of the lamp. The lamp base is shown as provided with the customary bayonet pin l4 adapted to be received in the customary bayonet channel I in the socket 9.

As shown in Figure 2, the endclosure wall of the housing I formed by the circular extension 4 is provided with a concentric circular opening It the edges of which are countersunk below the plane of the end wall. A shouldered sleeve I1 is passed through the opening with the shoulder thereof in engagement with the inner countersunk portion of the closure 4 with the metal of the sleeve on the outer side struck or spun over the outer surface of the end closure to secure the sleeve ll thereto. The bore H! of the sleeve I1 adjacent its outer end is increased in diameter to provide an annular shoulder l9 to receive a disc or lens 28, of transparent or translucent material, such as colored glass, which is held in engagement with the shoulder 19 by spinning or striking over the metal 2| of the end of the sleeve to engage the outer surface thereof. It is also preferable to provide the end of the bore l8 adjacent the lamp 10 with an outward flare 2| to concentrate and. direct the rays of light from the lamp to pass through the disc 20.

When it is desired to attach the housing I to be positioned at the rear of an instrument board of an automotive vehicle with the disc 20 visito act as a telltale light to indicate for example that the tail light is energized, that the lubricating oil for the motor is properly circulating, that the heater motor is operating or like purposes, an opening 22 is provided in the instrument 5 board 23 through which the sleeve I1 is passed to expose the disc or lines 20 to the vision of the driver. The exterior of the sleeve I1 is screw-threaded and the housing is secured tothe instrument board 23 by threading a nut 24 over. the portion of the sleeve l'l extending beyond the instrument board. It is also preferable to provide a nut lock washer 25 upon the sleeve ll between the rear of the instrument board 23 and I the housing closure 4 to hold the housing securely in 'place.

It will be noted that the housing I, extension 4, sleeve l1, and the disc or lens 20, are fixedly secured to each other so as to constitute a unitary article of manufacture assemblable with the panel 23 as a unit and disassemblable from the panel as a unit.

It will be understood that the disclosure herein is illustrative, and that my invention is not limited thereto.

What I claim is:

1. Mounting means for an electric lamp including a housing closed at one end and open at the other to receive a lamp socket, an opening provided in the closed end with means extending therethrough and immovably secured to the end closure projecting in prolongation of the housing adapted to direct the rays from the lamp when energized through said means, wherein said means is exteriorly screw-threaded upon the portion exterior of the housing and having a transparent disc secured therein, and wherein said means is adapted to pass through an opening in a support therefor and be engaged by a similarly threaded nut on the opposite side of the support to secure the housing thereto.

2. Means for mounting an electric lamp on a panel, comprising: receiving means for receiving and holding the socket for the lamp and forming a hood for the lamp; a tubular member integral with said receiving means and having an outside diameter less than that of said receiving means in the general plane of the panel, the junction of said tubular member With said receiving means forming an abutment; a lock washer disposed about said tubular member, and adapted to engage said abutment and one side of said panel, said tubular member being adapted to extend through said panel to the other side thereof; and means engageable with said tubular member and said other side of said panel to hold said receiving means in operative position.
